Purchased this lens (used) as a replacement for the kit lens.
My decision initially was between this lens and the 28-75. Chose the 24-135 based on the extra range as well as the very good reviews from this site. I have to say that I was fairly disappointed, mainly in the image quality. Wide-open, the kit lens produced better images. The Tamron improved at about f8, but image quality was not substantially better than the kit lens (and in most cases, worse). I took some comparison photos here:http://s91991420.onlinehome.us/lens-comparison/
